In automobile, engine art, the energy and environmental issue have promoted that it has improved environmental pollution effectively, has promoted the transformation of energy resource structure as the extensive use at city bus and taxi of the liquefied petroleum gas automobile of clean fuel.Adopt the automobile of single-fuel liquefied petroleum gas (LPG) at present as motor fuel, under the automobile normal operation, the cooling water of motor is by the cooling water inlet pipe inflow evaporator of vaporizer, because the temperature of cooling water is about 85 ℃, it is in the process of vaporizer of flowing through, its heat makes LP gas fuel preheating, evaporation and vaporization, flow out from the cooling water outlet pipe of vaporizer more afterwards, can guarantee to enter the abundant gaseous state of LP gas fuel of motor and the quantity that needs like this, make the motor proper functioning.But when the automobile cold starting, especially in the winter time, because the latent heat of vaporization of LP gas fuel is big, the LPG saturated vapour forces down, the cooling water temperature of motor and LP gas fuel self-temperature are also all very low, the cooling water that flows through vaporizer like this can't satisfy the liquefied petroleum gas (LPG) evaporation and the required heat of vaporizing, and causes the motor can not normal starting.
Adopt the single-fuel liquefied petroleum gas (LPG) can reduce environmental pollution at present as the automobile of motor fuel, alleviating energy crisis, but, therefore limited its application in the winter time because there is above-mentioned shortcoming in it.
Be to improve the reliability of single-fuel liquefied petroleum gas automobile motor cold starting, domestic developed resistance wire in succession and twined the LPG jar after the energising heating make the LPG vaporization, but this kind mode power consumption is huge, can exhaust the electric weight of automobile storage battery very soon,
Make motor be difficult to starting; Another kind is the engine cooling water external circulating system, earlier the cooling water of motor is extracted out at prestart and is carried out external heat, then cooling water is supplied with vaporizer, and this mode complex structure, cost height have limited it and applied.
Summary of the invention
The purpose of this utility model provides a kind of gasoline cold starting auxiliary device of single-fuel liquefied petroleum gas automobile.
The utility model is made up of with pressure governor assembly 18 and petrol tank 19 petrol jet 16, oily rail 17, petrol pump, and wherein petrol tank 19 is fixed in the automobile chassis; Oil rail 17 is fixed on the intake manifold 16, and the outlet with pressure governor assembly 18 links to each other its inlet with petrol pump by oil pipe, and its outlet directly links to each other with the inlet of petrol jet 16; Petrol pump and pressure governor assembly 18 are immersed under the liquid level of gasoline in the petrol tank 19, and petrol jet 16 is fixed on the throttle body 15.
The utility model is to supplying with the control of gasoline to intake manifold 14 through throttle body 15 by petrol jet 16, and control from intake manifold 12 to motor 13 that original liquefied petroleum gas (LPG) (LPG) fuel supply system is supplied with liquefied petroleum gas (LPG) (LPG) by, the shared control unit of the control section of the two (ECU) 23, and control unit (ECU) 23 passes through lead, one the tunnel links to each other with the petrol pump of petrol pump with pressure governor assembly 18, and another road links to each other with petrol jet 16.
Fuel supply system of the present utility model is independent of single-fuel liquified petroleum gas engine 13 original liquefied petroleum gas (LPG) (LPG) fuel supply systems.
Original liquefied petroleum gas (LPG) (LPG) fuel supply system by LPG jar 22, control unit (ECU) 23, control and information show 20, LPG adds gas port 1, combination brake switch and proporting 2, high-voltage tube transition piece 3, fuel cutoff valve 4, filter 5, cooling-water temperature sensor 6, cooling water inlet pipe 7, cooling water outlet pipe 8, vaporizer 9, combustion gas rail 10, gas nozzle 11 are formed.
Engine assembly is made up of intake manifold 12, motor 13, intake manifold 14, throttle body 15.
The utility model combines by the fuel supply system with existing single-fuel liquified petroleum gas engine, under the cold starting operating mode, control unit (ECU) 23 detects the temperature of the cooling-water temperature sensor 6 on the cooling water inlet pipe 7 that is installed in vaporizer 9, when this temperature is lower than a certain setting value, the control that control unit (ECU) 23 cuts off gas injector driver 26 in original LPG fuel supply system, connect simultaneously in petrol pump in the gasoline assisted cryogenic starting arrangement and the pressure governor assembly 18 guide line of petrol pump and the guide line of petrol jet 16, make the work of gasoline assisted cryogenic starting arrangement, guarantee the reliable starting of motor 13; When the cooling water temperature of motor 13 reaches setting temperature, the engine cooling water of vaporizer 9 of flowing through can satisfy heating, evaporation and the vaporization of LP gas fuel, therefore control unit (ECU) 23 is automatically converted to the work of LP gas fuel supply system, and cuts off the work of gasoline assisted cryogenic starting arrangement; Gasoline assisted cryogenic starting arrangement be for cold starting custom-designed, the emitted dose of petrol jet 16 and petrol tank 19 volumes are all less, can only be (as LPG jar 22 skies, when the LPG fuel supply system can't be worked under cold starting operating mode and emergent operating mode, with low speed, closely car is driven to suitable place) use, can not be applied to the cruising operating mode.
The utility model can guarantee that the cold-starting of single fuel fluid liquefied oil gas motor is reliable, even can be at-25 ℃ of normal startings.This system synthesis has been considered the emission performance and the preheat time of automobile, has that low cost of manufacture, investment for trnasforming urban land are few, component are easy to choose, and helps large-scale promotion application.
